Biologically inspired nanofibers for use in translational bioanalytical systems.

Electrospun nanofiber mats are characterized by large surface-area-to-volume ratios, high porosities, and a diverse range of chemical functionalities. Although electrospun nanofibers have been used successfully to increase the immobilization efficiency of biorecognition elements and improve the sensitivity of biosensors, the full potential of nanofiber-based biosensing has not yet been realized. Therefore, this review presents novel electrospun nanofiber chemistries developed in fields such as tissue engineering and drug delivery that have direct application within the field of biosensing. Specifically, this review focuses on fibers that directly encapsulate biological additives that serve as immobilization matrices for biological species and that are used to create biomimetic scaffolds. Biosensors that incorporate these nanofibers are presented, along with potential future biosensing applications such as the development of cell culture and in vivo sensors.
